Drosophila NURF-55, a WD repeat protein involved in histone metabolism.

The Drosophila nucleosome remodeling factor ( NURF) is a protein complex of four distinct subunits that assists transcription factor-mediated chromatin remodeling. One NURF subunit, ISWI, is related to the transcriptional regulators Drosophila brahma and yeast SWI2/SNF2. We have determined peptide sequences and isolated cDNA clones for a second NURF component (the 55-kDa subunit). Immunological studies show that p55 is an integral subunit of NURF and is generally associated with polytene chromosomes. The predicted sequence of p55 reveals a WD repeat protein that is identical with the 55-kDa subunit of the Drosophila chromatin assembly factor (CAF-1). Given that WD repeat proteins related to p55 are associated with histone deacetylase and histone acetyltransferase, our findings suggest that p55 and its homologs may function as a common platform for the assembly of protein complexes involved in chromatin metabolism.[1]
